"Okay, okay! Sincerity, right?"
Rias blushed as she looked at Li Ke.
Although she could not only kill Li Ke with ease, but she could even go as far as revealing her own weaknesses to him, her feelings towards him weren't what she perceived—that of an ordinary human. After all, to Rias, Li Ke was a special person.
This guy had helped her, and at least seemed to have no ulterior motives. If he wasn't the mastermind, but a genuinely ordinary person, then his honesty at least made him a good person.
She just couldn't afford to take the risk.
Therefore, besides repaying a debt of gratitude, Rias wanted to recruit Li Ke as her servant. There were other factors as well.
Li Ke stepped out of the bathtub with an air of nonchalance, and Rias blushed even more as she looked at his body.
However, having already decided to leave this world this way, Rias wouldn't hesitate any longer. She walked to Li Ke's side, squatted down, and, without much preparation, found Li Ke's energy, amplified by the power of this world, to be incredibly abundant.
Reaching out, she grasped the short sword. Rias opened her mouth, trembling slightly, but couldn't help closing her eyes..
After all, even as a Devil, she was still a girl who had never experienced anything like this. If Li Ke were her servant, she wouldn't feel so much pressure.
But just as she hesitated, Li Ke, seeing her like this, couldn't help but feel excited.
And so, the short sword, which had been some distance away from Rias, touched her trembling red lips.
"Ugh!"
Rias let out a soft cry of surprise, opening her eyes in astonishment. She instinctively licked her lips where Li Ke had touched them, but there was no strange taste, only the taste of water.
She glared at Li Ke, annoyed, but watching the short sword gradually extend, she took another deep breath and brought it to her tongue.
Then, the short sword swiftly evolved into a spear on her tongue!
Li Ke's first sensation was burning heat.
Rias's body temperature was significantly higher than normal. Not only that, her tongue was incredibly soft, feel as if it's alive.
Furthermore, her saliva was strange, much stickier than ordinary human saliva, and upon contact, it produced a burning sensation different from the heat from a kiss, yet it wasn't unpleasant; instead, it felt quite comfortable.
As expected of a Devil!
Li Ke's eyes lit up.
However, for Rias, it was also quite peculiar.
"This taste…"
The taste was very strange; for Rias, it was definitely not a pleasant taste, but her Devilish nature excited her.
Yes, she felt a surge of excitement. The thought of herself, the daughter of the Gremory family, the fiancée of the Phenex family, and the sister of the Devil King of the Devil World, now kneeling here doing this for an ordinary human filled Rias with a strange sense of excitement.
This excitement, somewhat akin to a feeling of betrayal, was quite comfortable for her. However, another ability of her bloodline immediately made her sense something was amiss.
"He gained magic power?! He was just an ordinary person before?! And his body has become stronger? His aptitude seems to have improved a lot? Did he obtain this in another world?"
Rias couldn't help but wonder. After all, the Gremory bloodline was known for its ability to find treasure among Devils.
Because her mind was preoccupied with other things, Rias unconsciously licked the tip of the spear that had entered her mouth, sucking on it in small sips.
This movement wasn't very large, making Li Ke feel as if he were being tickled.
If it were just for a short time, there wouldn't be anything wrong with it, but Rias forgot one thing.
Her saliva possessed a unique allure and power over mortals, and as a Devil, extraordinary charm was a standard feature.
Not to mention, when Li Ke looked down at her, he saw not only her slightly flushed cheeks but also her snow-white, alluring breasts.
Li Ke felt his desire completely aroused. With Rias's tongue constantly licking, Li Ke's heart felt like it was being tickled by a feather. Finally, he involuntarily grabbed Rias's red hair. The moment her smooth hair was grasped, the knowledge she had learned and her Devilish instincts prepared Rias. Her tongue instinctively curled, and her throat and mouth adjusted their positions, subconsciously ready to go.
Li Ke, however, was stunned. Rias's preparation was too perfect; he had intended to make her to prepare, but now, since Rias was already prepared, then Li Ke pressed Rias's head down without hesitation.
The spear easily entered what should have been food, but the Devil's body structure was indeed different from a human's. Although Rias showed some subtle nausea, Li Ke felt her throat involuntarily sucking and biting at him, and a tremendous suction force instantly surged forth, as if in a vacuum!
Li Ke instinctively tried to pull away, but Rias, as if by instinct, wrapped her tongue around the spear.
The next moment, the Black Rock Dragon's breath filled the cave, and Rias's tongue finally tasted something that was pleasant to her.
The fishy taste was quite enjoyable, and by the time she realized what was happening, she had already swallowed some.
Realizing herself, Rias immediately spat out Li Ke's spear, then lowered her head and spat out what was mixed with her saliva.
However, in doing so, some of Li Ke's breath also landed on her hair and face, and even her ample breasts were stained with the Black Rock Dragon's dragonfire.
This wasn't just because of shame, but also because of the dignity of the Gremory family's young lady.
After vomiting, Rias couldn't help but cover her mouth, belatedly coughing up white phlegm.
And Li Ke…
He was speechless.
Clutching his head, Li Ke couldn't believe it.
He had only penetrated once, and he had immediately been disarmed by the excessively pleasurable environment.
Was it because he had been using it too much lately, or because Rias was just too perfect?!
"I was so fast? Yes, it must be because Rias, as a Devil, she is just too amazing!"
Li Ke had to admit this; Devils and humans were different!
He would never admit that it was because he had done it too much with Tanjie that he had forgotten how to hold back!
After all, with Tanjie he didn't need to hold back!
She had a built-in delay potion!
Rias couldn't help but sneer.
"I think it's because you're too weak."
She glared at Li Ke, annoyed. Although she was prepared for his ministrations when he grabbed her hair, it was still quite excessive for him to shove a spear down her throat without asking permission!
While she was a typical pure-blooded Devil, years of intermarriage meant that no Devil family could guarantee they didn't have some succubus blood in their ranks.
Rias didn't care much about this; after all, succubus blood allowed her to better serve the one she loved.
Although she didn't yet feel she loved Li Ke, if it had to be done, then speed was the best approach.
So, using a little succubus technique was no big deal.
"Devil, you really are a Devil."
Although he wanted to go again—Rias's mouth was truly pleasurable, and he even wanted to try those large breasts—
But since he'd already said it once, that was it. Besides, Lux was coming up later, and keeping that girl waiting too long wasn't a good idea.
So, quite annoyed, Li Ke returned to his bathtub and continued washing himself.
Rias, meanwhile, casually rinsed her mouth, then looked at Li Ke soaking in the oil tub and spoke earnestly.
"So, now that the contract is established, you can show me your sincerity, right? Although the first time wasn't very successful, as long as it doesn't concern my purity, I'm willing to go wherever it takes until you've accumulated enough energy to send me back. As long as you don't go too far, I won't ask how much energy I've gained."
Rias said this almost with suppressed embarrassment.
"That's unnecessary."
Li Ke glanced at his energy level and then accurately stated the amount of energy Rias had given him this time.
"You gave me oral sex this time, and it only produced 70 energy points... You didn't put any emotion into it at all."
Li Ke really wanted to retort. Compared to Lux, Rias produced significantly less energy.
"Of course, you're not my lover. Why should I get too excited? Aside from the terrible taste, what's the difference between doing this with you and drinking milk tea through a meat straw?"
Rias spoke, clutching her chest. Her gesture was more like supporting her breasts because they were so large.
Li Ke's eye twitched. He understood the implication in Rias's words; she was still mocking him for ejaculating so easily.
"...Yeah, there really isn't much difference."
Although she had mocked Li Ke, Rias's heart was pounding. This experience made her blush and her heart race. She didn't know why she had been so tough in front of Li Ke; she simply didn't want to appear too ashamed or aroused—because she felt that would make Li Ke smug.
While there was nothing wrong with making Li Ke smug, she was still a little unwilling.
"Then I'll be leaving now. Remember our promise. I'll come over after you take Lux back."
Rias waved to Li Ke and swung her large breasts back to her room.
Li Ke watched her slender figure disappear, took a deep breath, and then continued washing himself.
Anyway, he wouldn't lose out. So be it.
After washing and rinsing off, Li Ke returned to his room.
"Lux, I'm back. We… um?"
Pushing open the door, Li Ke expected to see a shy Lux—and he did, but she looked completely different.
The black bodysuit that had covered Lux's slender legs was gone, replaced by smooth, long legs and fair skin.
Not only that, but her upper bodysuit was also gone.
But most importantly—
Water droplets clung to her buttocks, and the path leading to the garden was also stained with strange water droplets.
Li Ke's mind was a little confused. If he remembered correctly, he had said that her mouth would suffice, right?
This is…
"Mr. Li… Mr. Li Ke."
Lux's face was flushed, and she stammered.
"My mouth won't work anymore, so please use my back. I trust you, so, so…"
Li Ke's Black Rock Dragon raised its head.
"Um, actually, it's not necessary. I can take you back right now, Lux. And your hands and legs are probably fine too, it's not really necessary..."
He wasn't really comfortable with being behind her, because he'd heard some common knowledge that very few women experience pleasure from behind.
Furthermore, the intestines could get injured, and they're very rough, easily causing injury.
This kind of damage is irreversible, causing permanent damage and making one susceptible to diseases and parasites.
Most importantly, if it's not cleaned properly, wouldn't it just become a nuisance?!
"I...I cleaned it very well, Mr. Li Ke, and...and I'm worried about not having enough energy."
Lux reverted to her stammering manner, expressing her concerns.
She was genuinely afraid that after making her perform oral sex for so long, Li Ke would tell her she didn't have accumulate enough energy, so she figured it was better to take the initiative. If it satisfied Li Ke, then that would be best.
Li Ke: "..."
Li Ke sighed and walked over. Lux lay down beside him, presenting her cute, white, pert buttocks to Li Ke, letting him see the pink, constantly writhing muscles and the cool, moist droplets that oozed from her tender flesh.
After tentatively touching that soft flesh, Li Ke discovered—
Lux's lovely garden was seeping with moisture.
